Procedures Performed

Common outpatient procedures performed at this ambulatory surgery center, based on reported specialties.

Gastroenterology (GI Surgery)6
ColonoscopyA flexible camera examines the full length of the colon to screen for cancer and remove polyps before they become cancerous. Done under sedation, it typically takes 30 to 60 minutes. The bowel prep the day before is the part most patients find hardest.Upper Endoscopy (EGD)A thin camera passed through the mouth examines the esophagus, stomach, and the first part of the small intestine. Used to investigate persistent heartburn, difficulty swallowing, unexplained bleeding, or abdominal pain. Usually takes 15 to 30 minutes under sedation.Flexible SigmoidoscopyExamines the lower portion of the colon only, rather than its full length. Preparation is lighter than a full colonoscopy and sedation is sometimes unnecessary, but it cannot detect problems higher in the colon.Capsule EndoscopyYou swallow a vitamin-sized camera that photographs the small intestine as it passes through — a region that standard scopes cannot easily reach. There is no sedation and no recovery. The capsule passes naturally, and images are reviewed after the fact.ERCPCombines endoscopy and X-ray imaging to diagnose and treat blockages in the bile and pancreatic ducts, most often gallstones stuck in a duct. Unlike a routine endoscopy, it carries a meaningful risk of pancreatitis afterward, so it is used when treatment is likely rather than for screening alone.Hemorrhoid TreatmentShrinks or removes swollen veins in the rectum and anus using rubber band ligation, injection, or surgical removal depending on severity. Banding is quick and typically requires no anesthesia; surgical removal is more effective for advanced cases but recovery is noticeably more uncomfortable.

I can’t say enough good about my experiences here. From the front office to the doctors, nurses and assistants, they’re all super nice and very professional. Dr. Mayes is outstanding. I’m a high cancer risk person and she treats my situation with the utmost in knowledge and care. Highly recommended!

I arrived at the appointment a bit early; Dr Goldman came in right away. We reviewed details of a 2022 diagnosis, he reassured me we had several good options to get my issue under control and I wasn’t a high risk for anything terrible. I left the appointment feeling like we had a good plan in place. I have a great deal of trust in Dr Goldman. Excellent physician.

Always a caring team from reception to treatment. I can’t say enough about my experience with Elizabeth Hessler. She is the most knowledgeable and empathetic person I have ever met. Thank you for explaining my choices in words I could understand and making a difficult day a little easier!

I had my 2nd visit just a few days ago. I met with a nurse first who was wonderful. Then I met with Melanie, one of the NPs. I absolutely loved her. She took all, and it was a lot, of time to really understand what I have been going through, what I have tried for treatments and involved me 100% in decisions for my next steps. I only want to see her going forward. Even though the other staff is very friendly and accommodating.

Appt @ 1. Got there 1:03 person b4 me took 5 mins. Now its 1:08. I got reprimanded immediately and not sure if they can take me. Then I got in & I waited. Now I was being punished for being 3 mins late. I explained what time I was in line. When London came in, she was rude and didn't really want to hear what happened. She couldn't be bothered. That was after the 10 seconds I was commenting on that. She never looked at Anything except the computer. Asking me did you this, did you that. I quickly gave her my concerns and my history. She didn't hardly look at me. I commented on liking her glasses but never a smile. If I was older and I'm 75 yrs young, I would have felt shamed by all that. Ya know, like bad girl. I guess by 1:00 they had over 100 ppl that they saw There was only that One woman out front. I've coming there in and off for yrs. No one was Ever like that. So glad you asked Audrey Boisvert. The woman that cked me out was the best. So sweet & She smiled a lot
